中国天然气地质理论进展与勘探战略

六五”以来,以大中型气田勘探方向为重点所开展的天然气地质理论研究的主要进展是:(1)确立了中国含煤盆地转化为含气(油)盆地的地质条件及含气前景;(2)阐述了天然气多源、多阶段形成及运移多相态特点;(3)以热体制和地球动力学为基础建立的“盆、热、烃”理论进一步阐述了天然气生成的关键地质因素;(4)建立了以晚期、超晚期生烃、成藏为主的多种动态成藏模式;(5)总结了中国大中型气田的主控因素,提出了21世纪中国天然气勘探战略。

THEORY PROGRESS OF NATURAL GAS GEOLOGY AND STRATEGY OF GAS EXPLORATION

Major progress in the study of natural gas geology since the 6th five year plan are as follows: 1.put forward the geological theory of transformation from coal basin into gas(oil) basins; 2.put forward the multi source,multi stage and multi phase gas reservoiring theory; 3.put forward the “basin geotherm hydrocarbon”theory based on the thermal system and geodynamics; 4.put forward various reservoir models composed mainly of late and ultra late hydrocarbon generation and pool forming; 5.summarized main controlling factors of large and medium gas fields in China and the strategy of natural gas exploration in the early years of the 21th century.
